Firefox TypeError: wrappedCompareFn is not a function

Question

My build works in Chrome, Safari and Opera, but in Firefox. I use React, Webpack and Sass. The console error I get is: TypeError: wrappedCompareFn is not a function bundle.js:39813:24 as well as TypeError: node is null bundle.js:7865:1 Below I have included my webpack file and the dependencies in my package. Json Any help is much appreciated. Webpack:

const path = require('path');
const webpack = require('webpack');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const autoprefixer = require('autoprefixer');

module.exports = {

  devtool: 'cheap-module-source-map',
  entry: './client/src/App.jsx',
  output: {
    path: path.join(__dirname, './client/public'),
